Passage Four
Modem ideas are beginning to influence the Eskimos, but not enough to make much difference to their way of life. They still spend the winter in igloos, the round huts that are built of snow frozen hard. They still travel on sleds that are pulled by dogs. The winter is too cold for hunting, so during that season they live on the stores of seal meat that they have killed in the summer. But seal meat is not the only kind of food that they eat. In summer they hunt bears and reindeer, a type of deer With long branching horns that is used for its milk, meat and skin. They also fish all the year round. The Eskimos who are hunters in summer are fishermen in winter. In winter they make holes in the ice and catch their fish through the holes that they have made. The Eskimos are adaptable. That is why they are able to live in Arctic regions.
